Hi, I have an 02' 5.9 gas and I developed a severe antifreeze leak coming home from work today. It appears to be leaking behind the large pulley on the bottom front of the engine. My truck isn't getting above 130, due to the antifreeze leaking out. Any thoughts on what is wrong? (is this the front seal??) any idea stealer cost to repair this? thanks. I can't fix this in 0 degree weather/ice in my driveway and I need my truck for work.

 

That would be your water pump. You need to replace it.

 

Yeah, you should be able to look under the truck up at the front of the engine and see where it is coming from but the water pump is most likely.

 

That would be your tell-tale...it is telling.
